Skip the battery device name reading on BQ27742
Contrary to the BQ2751 and BQ27741 it is sharing code with, BQ27742 does
not have a "device name" register. So we need to skip the I2C reads else
the battery_device_name() function returns an I2C error and the charge
code retries until the end-of-time to read it hogging the CPU.

BUG=chrome-os-partner:38401
TEST=run on Ryu P4 and verify that we are no longer seeing 20ms of I2C
transactions every 100ms on the battery I2C bus.
